Question

The p-value

a) can be any negative value.
b) can be any positive value.
c) must be a number between -1 and 0.
d) must be a number between zero and one.

Answer 1

The p-value is a number between zero and one and represents the probability that an event will happen purely by chance assuming the null hypothesis is true.

Step-by-step explanation:

The p-value is the probability that an event will happen purely by chance assuming the null hypothesis is true. It is a number between zero and one, so the correct answer is d) must be a number between zero and one. When the p-value is very small, it means that the observed test statistic is very unlikely to happen if the null hypothesis is true. This provides evidence to suggest that the null hypothesis is false, and we reject it in favor of the alternative hypothesis.
